DS150i/DS151i Installation Guide Request-to-Exit PIR Detectors
1.0 Description
The DS150i is a passive-infrared detector designed for request to exit
(REX) applications. It is UL Listed as an access control device under the
UL 294 standard and is listed for Class I for UL Canada (ULC-S319). For
C-UL listed installation applications, the REX shall be connected to ULC-
S319 listed compatible devices (i.e. control units, power supply and
locks). Intended for indoor use only.
The relay output consists of two Form "C" contacts that can be adjusted to
latch from approximately 0.5 sec to 64 sec. The latch time features two
modes of operation: resettable (R) and non-resettable (NR). The relay can
also be programmed to fail safe or fail secure during a power loss.
You can mount the DS150i on the ceiling or wall and aim and/or mask its
pattern for more effective use based on installation needs. The DS150i is
not designed as the primary means of exit for emergency egress
applications.
The DS150i is available in a light grey (DS150i) or a black (DS151i)
enclosure. An optional trimplate is also available in light grey (TP160) and
black (TP161).
2.0 Mounting
1. Select a mounting location over the center of the door or doors to be
covered. The target must walk directly toward the detector.
Mount the detector on the ceiling, wall, or door frame. The detector
can be surface mounted or mounted to a keyswitch plate with a "D"
size hole.
The DS150i is not tall enough to completely cover a single
gang box. Where aesthetics are important, mount it using
the optional trimplate (TP160 or TP161). Refer to Figure 1
for additional instructions for mounting with the trimplate.

The arrows on the base indicate its correct mounting
orientation relative to the door.
The mounting height range is from 7 ft to 15 ft.
(2.1 m to 4.6 m) above the floor.
2. Remove the back cover from the detector. Insert the head of a small
straight edge screwdriver into the locking tab and pry the back cover
off.
When the back cover is removed, the front cover and
detector module separate.
3. Route the wiring as necessary through the wiring entrance (refer to
Figure 2). For surface wiring, use the break out wiring entrance on
the front cover (at the same end as the wire entrance).
4. Loosely mount the back cover to the mounting surface using the
supplied mounting screws.
5. Mount the detector module to the back cover. Aim the detector for
the desired coverage.
Coil excess wiring behind the back cover along the
channels provided.

3.1 General Information
Only apply power after all connections are made and
inspected. Remove all system power (AC and standby
battery) before wiring the device.
Attach the wiring connector (provided) to the wire plug on the circuit board
(refer to Figure 3).
Figure 3: Connector to Plug Orientation (Default Switch Settings)
Refer to Figure 4 to wire the detector’s relay contacts.

3.2 EMF (Voltage) Spike-Protected Relay
Pins 6 through 8 (wire colors gray, green, and orange) comprise the EMF
spike-protected relay. Refer to Figure 3.
Use this relay when connecting inductive loads to the detector. This relay
protects the detector from inductive loads that might deliver damaging
EMF spikes.
3.3 Non-EMF (Voltage) Spike-Protected Relay
Pins 3 through 5 (wire colors yellow, violet, and blue) comprise the non-
EMF spike-protected relay. Refer to Figure 3.
This relay is best used for non-inductive loads. When connecting an
inductive load that is not spike-protected, such as a magnetic door lock, to
the detector, use either a bridge rectifier (such as a KBL01) or a diode
(such as a 1N4007). Failure to use a bridge rectifier/diode may reduce the
lifetime of the relay. Refer to Figure 5.

(non-spike protected)
UL 1034 listed magnetic locks typically are already EMF
spike-protected, and therefore do not require the bridge
rectifier or diode as shown in Figure 5. Adding a bridge
rectifier/diode to an EMF spike-protected device can cause
unwanted delays in response. Refer to the magnetic lock’s
documentation for more information.
4.0 Configuration
Use the on-board DIP switches to configure the operation of the detector.
Refer to Figure 6 for proper switch positioning.

4.1 Resettable/Non-resettable Timer Selection
DIP Switch 1 determines if the relay resets at the end of latch time, or if
latch time is extended by additional motion. Refer to Table 1 and Figure 6
for more information.
Resettable: The relay activates when the detector first sees motion.
Any additional motion restarts the latch timer so the relay deactivates
only when the detector no longer sees motion and the latch time has
expired. Hint: This setting works best when bypassing a 24-hour
contact.
Non-resettable: The relay activates when the detector first sees
motion. It deactivates when the latch time ends, even if motion is still
present. Hint: This setting works best when used with an access
control system.

OFF Non-resettable
ON Resettable (Default)
4.2 Relay Mode
DIP Switch 2 selects the relay mode. This allows you to select a fail safe
by default, or a fail secure mode. Refer to Table 2 and Figure 6 for more
information.
Fail Safe: In the event of a power loss, the REX detector releases
the device connected to it (for example, magnetic door lock or
electric door strike).
Fail Secure: In the event of a power loss, the REX detector does not
release the device connected to it (for example, magnetic door lock
or electric door strike).
In Fail Secure mode, the REX detector shall be installed in a manner
that does not impair the intended operation of panic hardware used
in conjunction with the REX detector.
Failure Secure mode must be authorized by the local Authority
Having Jurisdiction (AHJ).

Switch 2 Function
OFF Fail Secure
ON Fail Safe (Default)
Refer to Figure 4 relay wiring options.
4.3 Led Enable/Disable
DIP Switch 3 selects whether the on-board LED is enabled or disabled. If
enabled, the LED operates normally when motion is detected.
Table 3: LED Enable/Disable DIP Switch Settings
Switch 3 Function
OFF Disabled
ON Enabled (Default)
When LED is enabled, it will flash on and off when first
powered up. Once the flashing LED stops, the REX is
ready to be used.
4.4 Latch Time
DIP Switches 4, 5, and 6 set the relay latch time. Latch time is adjustable
from 0.5 sec to 64 sec. It indicates the amount of time the relay can
remain active after the detector first sees motion.

5.0 Setup and Testing
1. Apply power to the unit.
2. Wait at least 3 min for the detector to settle.
3. Test the unit by walking directly through the coverage area, toward
the door.
4. Aim the detector up or down if necessary to obtain the proper
coverage. Tighten the screws after aiming the detector.
5. Check that the relay latch time is sufficient. Adjust if necessary.
6. After confirming proper operation, replace the cover and walk test
one more time to ensure the coverage has not changed.
6.0 Other Information
Single Door Use: The pattern can be masked to remove the outer
zones using the supplied masking kit. Snap the masking wedges into
place on the outer surface of the lens (refer to Figure 7). The
masking wedges eliminate zones A, B, K, and L.
Figure 7: Pattern Masking
Testing: Test the detector a minimum of once each year to ensure
continued operation.

8.0 Application Notes
8.1 General
Double entry/exit doors without a center post present a problem resulting
from a gap that might exist between doors. While the gap is usually filled
with soft or pliable weather stripping, there is an opening that vandals can
use to insert an object (such as a comb or ruler) through and into the
coverage pattern of the detector. If the object is a different temperature
from the background, the DS150i interprets the temperature change as a
request to exit. Install a DS150i over the center of double doors with a
center post.
When there is no center post, consider an alternative mounting option to
move the center of the pattern away from the gap.
8.2 Ceiling Mount
Mount the DS150i to the ceiling and away from the door. Longer objects
can still be used to enter the coverage pattern. This type of entry would
now be much more difficult.
8.3 Dual Mount
Install and center one DS150i over each of the two doors and wire the
outputs so either detector permits exiting. Reduce the probability of
interference from foreign objects by masking out the inside zones (K & L
on one detector, A & B on the other detector). Refer to Figure 10.
